What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Proton beam therapy (with or without photon beam radiation)
What this could lead to
If successful, this could show that proton beam therapy is an effective way to control skull base chordoma and delay or prevent tumor regrowth after surgery.
What could go wrong
This is a small, early-phase trial with only 19 participants, so results may not apply to everyone. The study is also no longer recruiting, and it is not yet known if this treatment is better than standard options.
